Re: Install a 16 Tooth Front Sprocket
 

OK, your gonna have to explain that a bit; you lost me completely.

From your speed chart, though, if you are "normally" doing 60 in 3rd and 70 in 4th, you are working the engine WAY too hard.......to achieve a reasonably long engine life, that is.
We have had a couple of riders on here that worked the engine WFO all the time and the engine was shot around 20K miles. Those speeds are OK once in a while under difficult conditions but not ALL the time.

There is no need to wind it out that much, under normal conditions, as it WILL pull 60-65 easily in 5th (if you get it up to about 55 in 4th) and will do 70 on the flat but it takes a while. If you wanted something that was FAST, you got the wrong bike and changing out the sprocket might be a mistake for you.

With the 16T you get more range and better use of the torque in the lower gears at the expense of the top end, which becomes HP limited as you just can't get the revs. up enough.

Your previous post indicated that you were happy with the new setup. Have you changed your mind ??

Re: Install a 16 Tooth Front Sprocket
 

The speed chart was to give folks that don't have the 16 t an idea of possible top speeds.
I understand perfectly how the bike works with the new gear.

As far as backing off the throttle.....you have more throttle than the bike can use.
I roll on the throttle, then just back it off until the bike is just pulling, then add a little more throttle..
NOT just WOT.

Got it. Very true until you get the rev's up.
Is that "new" with the 16T or just worse?
I suspect it also did that some when stock but don't really remember.

With the 15t, it never quit pulling.
As you well know, completely different riding style.

Re: Install a 16 Tooth Front Sprocket
 

what do you guys mean by "pulling"

overall horsepower?

Re: Install a 16 Tooth Front Sprocket
 

Yes. In top gear, under "normal" conditions, with the stock gearing, the engine will pretty much keep going faster the more you open the throttle all the way to the end....or very near the end.
With the higher gearing, in top gear you run out of HP somewhere around 1/2 to 3/4 throttle and additional throttle produces......nothing in additional speed. In truth you are gaining a tiny bit under most conditions but past a certain point the speed increase is VERY slow.

This disadvantage is offset by being able to stay in the lower gears longer (to a higher speed) because you are not HP limited there. Cruising is also more comfortable at the slightly slower engine speed........as long as you are content cruising at 65 mph or less.

ahhh Perfect...

I understand the 16tooth fully now..

I totally forgot the gz could pull til the end with a 15t...its been awhile since i had it on


Made a few highway trips and wondered about another bike because of it but am always reminded when i re-read a post on here of why I chose to do it and what the conclusion is...

A bike that cant reach its highest speed potential which is much higher then posted speedlimits while also reducing the adverse effects of riding this sweet little bike hard...

in the end Gas is saved. and perhaps alot of the engine components due to the restrictions the 16tooth's gearing creates for the engines end power.

Pretty cool stuff.

Re: Install a 16 Tooth Front Sprocket
 

Just a quick question regarding the 16t sprocket, does anyone know if it'd fit inplace of the 15t sprocket on the 125? It seems there's no info on the 125, sofar I have had nothing but good coversations on here so you must be a real bunch of bikers, instead of other sites where they're just "talking the talk"

Re: Install a 16 Tooth Front Sprocket
 

My guess is yes but my advice is: Don't do it.

The 250 is on the verge of being overloaded with the higher gearing.
My guess is that 125 would not like it at all.

On the 250, the cover comes off the front sprocket with just 2 or 3 bolts. It's really easy to take a look and see how much space there is.

If you DO decide to experiment with the sprockets, count teeth on the original first. You may not have a 15 to start with.

where can i purchase a 16t sprocket online?
